On wood. Tasmania; Sweden. 



Sporangia '5 1 mm. diameter. Rostafinski founded his 

 Prototrichia elcgantula on a specimen in the Berkeley Herbarium 

 at Kew, which was sent by Fries, and marked " (Perichaena ?) 

 nova species, in Betula, Lindblad." This specimen on examin- 

 ation proves to be identical with Trichia metallica, B. The 

 last-named species is given as a synonym of P. flageUifer, B. 

 and Br., by Rostafinski, the outcome of superficial examination. 



Prototrichia bombarda, Mass. 



Sporangia broadly fusiform or elliptical, several seated on the 

 apex of an elongated stem, smooth, dark-broum, sometimes with 

 a purple tinge ; stem same colour, hollow, springing from a 

 well-developed hypothallus ; mass of elaters and spores brown ; 

 elaters cylindrical, 6 7 p thick, sometimes furnished with one 

 or two swollen portions, walls thin, collapsing when dry, un- 

 branckcd, with a few scattered, very rudimentary spinules, and a 

 very indistinct open spiral, free ends obtuse, rarely attenuated 

 and bifid ; spores globose, smooth, 5 6 p. diameter.
